Q. Re: addressing envelopes containing invitations to a married couple,

the female member of which is a doctor (1 November). When I was young we were told that you should address an envelope to one person only as only one person could open an envelope, unlike a letter that more than one can read. Therefore V.H. can address a letter to Dr Mary Smith (if it is a business or semi-business letter) and Mrs John Smith for social purposes.

S.S., Bickton, Hants A. Thank you for making this valid point.
